Cloud Native Theater | EnvoyCon: The Next Generation of Envoy Extensibility: Dynami... Rohit Agrawal

This talk covers the evolution of Dynamic Modules in Envoy, transitioning from an HTTP-only feature to a full-fledged extension mechanism across the filter pipeline. The speaker, Rohit Agrawal from Databricks, discusses the new Listener Filter and Network Filter support introduced in version 1.37, as well as enhancements in HTTP Filter capabilities such as streaming body manipulation and per-route configuration. The architecture is examined, highlighting how the C-ABI maintains compatibility while the Rust SDK ensures a safe and idiomatic developer experience. The session includes live demonstrations of a Listener Filter for protocol detection and a Network Filter for TCP stream manipulation, along with insights into the roadmap for ABI stabilization and multi-language SDK development.
